Abstract

This work investigates the effect of γ-irradiation on the dielectric properties and electrical conductivity of polypropylene (PP) composites filled with CdS + ZnS at various volume fractions (10%, 30%, 50%). It was found that, for pure PP and composites with a low filler content (up to 30%), the permittivity and specific resistance remain stable at irradiation doses of up to 50 kGy. At a dose of 80 kGy, an increase in permittivity is observed in samples with 10–30% filler, which is associated with an increase in polarization and the formation of cross-links. In composites with a high CdS + ZnS content (50%), the permittivity first increases to 9.3, and then sharply decreases to 7.1 at 80 kGy, which indicates the destruction of the polymer matrix. The specific resistance at high filler content is significantly reduced by γ-irradiation, especially at 50% filler, which is associated with the formation of conductive channels.
